| Résumé | (disponible en anglais seulement)
Several gold deposits and prospects in the Canadian Cordillera of British Columbia and Yukon are associated, at least spatially, to major fault zones. The
Llewellyn fault and Tally Ho shear zone region of northwestern British Columbia and southern Yukon is the locus of a series of vein-hosted gold prospects and deposits, including the past-producing Engineer and Mount Skukum mines. Many of these gold
occurrences have epithermal polymetallic signatures, although some are considered mesothermal-orogenic, as such related to first-order crustal breaks and synchronous magmatism. However, the temporal and genetic relationships between the orogenic- and
epithermal-style systems along the Llewellyn fault and Tally Ho shear zone remain to be clearly established. Reconnaissance work has underlined a three-part relationship between these large-scale structures, gold mineralization and Eocene magmatic
complexes. Characterization of Llewellyn fault zone in the Bennett Plateau and Tagish Lake area of British Columbia, and of the Tally Ho shear zone in the Tally Ho Mountain, Gold Hill and Mount Hodnett areas of Yukon, and of their spatially
associated gold mineralization, aims to test this model and ultimately draw comparisons with the much older, structurally controlled gold deposits of the Archean and Paleoproterozoic. |
